Beautiful orchids! Looks like you made out quite well! I have a couple of bellinas (one of them was the very first species phal I ever bought!), and if you're looking to compare them to NOIDs, I'd say the biggest difference is the rate of growth. I've got TONS of NOIDs, and they grow way faster than my species phals. Don't be surprised if your bellina just sort of sits around and does nothing for a while...that's pretty par for the course with species phals. But if you've got the culture down pat with your NOIDs, I don't think you'll have any problem at all with caring for your bellina. You'll know what to do.
Congrats on your new plants! Gorgeous!
